Posted by Adena Leigh

Helen Mirren

In 2018, Dame Helen Mirren arrived draped in jewels worth more than most people's entire net worth! Her cushion-cut sapphire and diamond necklace, with matching earrings (both by Harry Winston) ring in at a whopping $3.8 million. Flaw-less.

Angelina Jolie

When Angelina Jolie walked the 2009 Oscars red carpet in a pair of now famous emerald-drop earrings, it went down in history as one of her best (and most expensive) award show looks ever. The 115-carat Lorraine Schwartz stunners cost a cool $2.5 million. With their brilliant colour and shine, we can’t say we’re surprised!

Charlize Theron

It’s no wonder that a set of diamond cuffs were the perfect complement to Charlize Theron’s elegant white Christian Dior Haute Couture gown at the 2013 Academy Awards–after all, they’re worth $4.5 million!

Anne Hathaway

When Anne Hathaway co-hosted the 2011 Oscars with James Franco, her outfit changes (seven, to be exact) were some of the most anticipated highlights of the evening. She started the night off sparkling in a $10 million Tiffany & Co. Lucida Star diamond necklace with an estimated weight of 94 carats. With a necklace that expensive (and unbelievably gorgeous) we can’t help but label her red Valentino gown the accessory, and crown her diamonds the star of the show.

Nicole Kidman

Talk about wow factor! The Aussie beauty’s cascading diamond necklace at the 2008 Academy Awards was custom-made just for her by L’Wren Scott. The $7-million necklace featured more than 7,500 diamonds and was reported to have taken 6,200 hours to hand craft.

Jennifer Garner

Leave it to Neil Lane to create one of the most expensive pieces of jewellery on the 2013 Oscars red carpet. Worn by Jennifer Garner, the necklace’s dazzling diamonds were set in darkened platinum for a gorgeous vintage look. The lucky star was dripping in a total of $2.5-million worth of Neil Lane jewels that evening.

Gloria Stuart

A brilliant 15-carat blue diamond necklace by Harry Winston is hands down the most expensive piece of jewellery ever worn on the Oscars red carpet. The dazzling deep blue diamond is reminiscent of the famous Heart of the Ocean, and was appropriately worn by Gloria Stuart, Best Supporting Actress nominee at the 1998 Oscars for her role in Titanic.

Kate Winslet

We’re not sure what we were more excited to see on the 2010 Oscars red carpet: the beautiful Kate Winslet or her rare (did we mention enormous?) yellow diamond necklace made by legendary jeweller Tiffany & Co. The $2.5-million necklace was paired with matching $975,000 canary diamond earrings and bracelets, also by Tiffany & Co. We’ll have one (or two, or three) of each, please.

Amy Adams

The stylish American Hustle star donned some serious frosting at the 2011 Academy Awards. She wore a total of $1.3 million in Cartier jewels, including a platinum and diamond emerald secret watch bracelet and matching necklace.
